It is a problem when I install this plugin on the existing multi-site, I can't get the image on the subsites.
I suggest we can check the image before it returns the result on wp_get_attachment_image_src filter function. If the image array is empty after switched to the media site, we can get the image from the current blog.
Thanks for the report. This is not a use case that this plugin will support because it greatly increases the complexity. I recommend checking out the alternatives.
